What Are the Characteristics of Polyester Sound-Absorbing Cotton?

Product technology of polyester sound-absorbing and sound-insulating cotton: Polyester fiber sound-absorbing and sound-insulating cotton, made of polyester fiber, made of cocoon cotton after hot pressing. The heat treatment method is used to achieve density diversification and make it a sound-absorbing material and a decorative material without volatile matter. Polyester sound-absorbing and sound-insulating cotton is composed of two polyester fibers with different melting points. In the production process, when the oven is heated to the melting point of the low-melting fiber, the low-melting fiber is melted into an adhesive, which is formed after hot pressing. This is a new development developed to replace glass fiber, rock wool, sponge and other sound-absorbing materials. 

The sound absorption of polyester sound-absorbing and sound-insulating cotton: three-dimensional mesh-like porous material, and the pores are connected to each other. When the sound enters the material, the pores collide with each other. After friction, the sound energy is converted into heat energy, which effectively suppresses the sound. Make the sound fuller and rounder.

Sound-absorbing and sound-insulating cotton is widely used in concert halls, theaters, recording studios, studios, meeting rooms, gymnasiums, exhibition halls, dance halls, KTV private rooms and other public places. It can absorb noise and prevent indoor sound. Strong reflection affects the indoor environment.

Environment-friendly sound-absorbing and sound-insulating cotton: It is a new product developed to replace harmful sound-absorbing materials such as glass fiber and rock wool sponge. It is the most efficient natural sound-absorbing and sound-absorbing material that is closest to nature and harmless to the human body and the environment. In Europe and the United States, polyester sound-absorbing and sound-insulating cotton is fully used, and it is used in piano rooms, mechanical rooms, conference rooms, gymnasiums, concert halls, recording studios, soundproof walls and other public places to completely replace harmful sound-absorbing materials such as glass fiber and rock wool sponge. Dongguan Zhicheng Fiber Products' sound-absorbing cotton sound insulation cotton is compounded with various types of boards to increase the amount of sound insulation of walls and floors, increase the bandwidth of loud sound, and reduce noise.
